heating purposes, it being the object of the invention to improve uponprior types of furnaces 1I1 simplicity of construction, and in reduclngthe number of parts. It is an object of my present construction toimprove,

several features of existing types of furnaces inproviding easy meansfor cleaning out the passages which form the radiator of the furnace,the parts being so arranged that the dirt may be removed and droppeddirectly into the fire box. A further object is to shape and design theparts so that a separate fuel feeding passageway and door opening may beavoided.

In constructions which have preceded my invention, a separate fuel.feedingpassageway or pouch has been secured to the front of theradiator and combustion chamber, but

owingto the rapid changes in temperature and uneven expansion of theparts in the firing of the furnace, the bolts for holding the fuelfeeding passageway-in place have often been sheared off by the movementof the parts. It is one of the principal objects of'this invention to doaway with a separate element to form the fuel feeding'passageway so thatfaulty construction will be avoided.

In the drawings which accompany this applicationfthere is shown. theupper sections of the furnace, the lower portions and the casing beingofany standard or'well known construction and therefore, not beingilluse portion of the furnace'looking'in at the door opening or fuelfeedlng passageway.

V Fig. 2 is avertical section across the upperpart of the furnace onthe. llne 22 of F 1g. 3.

F 3 is a vertical section on the line of F 1g. 1. g

Fig. '4: is a horizontal section on the'line 4-4 of Fig. 3, looking downon the lower.

radiator section.

The furnace is built up of a plurality of cast iron sections as isusual, comprising a fire box 1, the upper edge of which is provided withan offset flange 2, in which is seated the lower edge of the combustionchamber 3.. I

The upper portion of the combustion chamber is curved or archedinwardly, and around its upper edge is formed a channel. orgroove 4.Above the combustion chamber is located the radiator which is made intwo sections divided on a horizontal plane.

The lower section of the radiator is designated by the numeral 5 and theupper section by the numeral 6, the lower edge of the uppersection beingprovided with an offset flange 7 which surrounds the upper edge of thelower section, the two sections being pro vided with registering lugs 8through which pass bolts 9, holding the two sections together. Theradiator shown in the drawings is .ofthe horse-shoe type, being providedwith a centrally located dome 10, curved smoke fiues 11 and a smoke pipecollar 12,

through which the products of combustion pass to the chimney The smokefines are open at the front as at'13'andare'easi1y accessible from thedoor opening. Incleaning out the radiator the soot may be raked to thefront of the fines and will drop directly into the fire box. p Thefuelpassageway and door opening, which is-indicated by the numeral 14 isformed integral with other parts of the furnace which have beendescribed, this being one of the important features ofmy inven- 1 tionas it does away with the separate'pieee or element to form a fuelfeeding passage way, a feature not found in prior furnaces of this type.This fuel feeding passageway is formed by extending from the frontportion of the combustion chamber 3 a U-shaped or channel-shaped flangeor extension 15 which forms the lower half of the fuel'feedingpassageway and providing. the lower radiatorsection 5 with a matingU-shapeol or channelshaped extension'16, the two extensions-ta.

getherforming' the fuel feeding passageway or door opening, as shown inFig. 1.

Thegroove or channel 4 is carried around on the upper edge of the part15, so that the extension in the radiator may seat therein. Across thefront of the extension 16 is car ried a pin 17 which swingingly supportsa door or shutter 18. The shutter 18 directs the products ofcombustion'into the flue 13 and diverts them from the upper portion ofthe door opening.

It will be understood that the furnace outer casingis placed around thefurnace in the usual manner, as shown in dotted lines in Fig. 4: at 19.Midway of the fuel feeding passageway 14 are a number of lugs 21 whichare used for supporting the inner casing 22, should it be desired to usethis furnace in the double casing or pipeless construction. j

The operation and advantages of the improved furnace will be readilyunderstood and appreciated. The smoke flues 11 are easily cleaned out byreason of the access provided from the door opening into the flueopenings 13. In prior constructions of this type, the extension whichforms the door opening and fuel feeding passageway was made in a singlepiece separate from the other parts of the furnace and secured to thebody of the furnace by bolts or similar means. As a result of the rapidand violent expansion and contraction to which these parts aresubjected, in the operation of the furnace, the holding means wouldoften be broken or loosened. In the furnace embodied in this inventionhowever, the fuel feeding passageway is made integral with the body ofthe furnace, by forming it from two extensions, the one on thecombustion chamber and the other on the lower half of the radiator andthe breakage due to the action obtained in the separate construction ofthe fuel feeding passageway is avoided. By forming the two sets of lugs20 and 21, the former for the front and the latter for the inner casing,the furnace is adaptable for either the pipe or pipeless construction.

It is obvious that changes and modifications may be made and form andproportion are not essential to the invention herein disclosed, but maybe varied without departing from the invention or sacrificing any of itsbenefits.

I claim:

1. In a furnace construction, a combustion chamber, a radiator above thecombustion chamber, said combustion chamber being open atone sidethereof, an integral extension about the opening to form a part of the'fuel feeding passageway, and means connected with the radiator locatedover the extension from the combustion chamber to complete the fuelfeeding passageway.

2. In a furnace construction, a combustion chamber, a radiator above thecombustion chamber, the combustion chamber and the radiator being openat one side, an integral extension about the opening in the combustionchamber, and an integral extension about the opening in the radiator,the said extensions together forming a fuel feeding passageway.

3. In a furnace construction,a combustion chamber, a radiator above thecombustion chamber, said radiator being open at one side, the flueopenings for said radiator being open adjacent the aforesaid opening inthe radiator, and an integral extension about the radiator openingforming a por tion of the fuel passageway.

l. In a furnace construction, a combustion chamber, a radiator abovethecombustion chamber, said radiator being open at one side, the flueopenings for said radiator being open adjacent the aforesaid opening inthe radiator, the combustion chamber being ope-n below the radiatoropening and forming therewith a feed opening and an extension about thefeed opening forming a feeding passageway, said extensionbeing in twoparts integral with the combustion chamber and the radiator.

5. In a furnace construction, a combustion chamber, a radiator above thecombustion chamber, said radiator being open at one side, the flueopenings for said radiator being open adjacent the aforesaid opening inthe radiator, anintegral extension about the radiator opening forming aportion of the fuel feeding passageway, and a shutter traversing saidextension.

6. In a furnace construction, a combus tion chamber, a radiator abovethe combustion chamber, said radiator being open at one side, the flueopenings for said radiator being open adjacent the aforesaid opening inthe radiator, the combustion chamber being open below the radiatoropening and forming therewith a feed opening, oppositely faced U-shapedextensions on the radiator and on the combustion chamber forming a fuelfeeding passageway, said extensions being integral with the radiator andthe combustion chamber, respectively.

7. in a furnace construction, a fuel feeding passageway extendingoutwardly from the combustion chamber, said passageway being formedthroughout its entire extent from the door opening to the furnace bodyby integral extensions from the furnace body, lugs on the outer edge ofthe extension adapted to hold the outer casing, and lugs on theextension between the first named lugs and the body of the furnace tohold an inner casing.
